Salsa is a 13-year-old female student from Dordtgard and the shortest member of unit IV KLORE at 141 cm tall. She possesses short, messy tawny hair with cowlicks resembling animal ears, piercing red-pink eyes, and visible fangs when she speaks. Her typical attire is her school uniform paired with white socks and black Mary Jane shoes.

As a werewolf, Salsa wields superhuman strength, speed, and an acute sense of smell. These abilities make her the track and field team's ace, driven by her love of running. Her strength proves exceptional for her age in combat, and she exhibits extreme resistance to toxins, evidenced by surviving ingestion of a lethal poisonous mushroom. However, she occasionally struggles to control her strength, leading to accidental damage.

Salsa displays a lively, carefree, and self-assured personality. Constantly energetic and in motion, she makes friends easily. She harbors a distinctive habit of creating and maintaining secret ranking charts categorizing peers by traits like reliability or threat level. She enjoys Dordtgard sausage and strongly dislikes dog food.

Her relationships include being childhood friends with fellow IV KLORE member Emilia. She shares a close, harmonious bond with her more reserved roommate, Kaede; Salsa's rambunctious athleticism contrasts yet complements Kaede's fondness for fluffy creatures, resulting in frequent physical affection like hugging.

Salsa utilizes her heightened sense of smell to help Kaede locate a missing person in a forest. She participates in IV KLORE's musical performances, including singing "Midnight Sapphire" during the Ceaster Festival, often energizing the audience through innocent MC segments.

She enrolled at Flora Girls' Academy as a disciple of Camilla, a former member of the disbanded unit Ray, establishing her magical education context.
